Filed: 1925-02-21
Abstract: 249,983. Vickers, Ltd., and Etchells, J. Feb. 21, 1925. Regulation, automatic; controlling heating systems.-In a heating system, for example for railway vehicles, in which the number of heaters 1 in use may be varied by short-circuiting switches 5, the dynamo current is automatically kept constant.

Title: New organic phosphorus compounds and process for their manufacture
IPC: D06M13/282
Filed: 1958-02-14
Abstract: The invention comprises products of the formula:  <FORM:0863380/IV (b)/1> wherein A1 and A2 are organic residues which are bound by a carbon atom to the phosphorus atom either directly or through an oxygen, sulphur or nitrogen atom, R is a hydrogen atom or a C1-C4 alkyl group and Z is an oxygen or sulphur atom.  A1 and A2 may each be an aliphatic, cycloaliphatic, aromatic, araliphatic or heterocyclic residue. The products may be obtained by reacting an amide of pentavalent phosphorus of the formula:  <FORM:0863380/IV (b)/2> with chloral.  The amido compound used as starting material may be an ester of amido phosphoric acid of amido thiophosphoric acid or of amido dithiophosphoric acid, an ester of a diamido phosphoric (or thiophosphoric) acid, an N-substituted triamide of phosphoric or thiophosphoric acid, an ester of an amido phosphonic (or thiophosphonic) acid, or an amide of a phosphinic or thiophosphinic acid.  The reaction may advantageously be carried out with equimolecular proportions of the reactants and at 30-100 DEG C. and an inert solvent may be present, e.g. an aliphatic or aromatic hydrocarbon or chlorohydrocarbon, an ether, e.g. dioxane or tetrahydro-furan, or a saturated amide which contains no hydrogen atom on the amide nitrogen atom, e.g. dimethyl formamide.  The reaction is preferably carried out in the presence of a basic condensation catalyst e.g. triethylamine, pyridine or dimethyl-aniline.  The products are useful as pesticides (see Group VI), flame-proofing agents (see Group VIII), textile assistants and lubricant additives.  Examples are given for the production of compounds of the above formula in which R is hydrogen, Z is oxygen, and A1 and A2 are each CICH2CH2O, C2H5O, and p-chlorophenoxy respectively.ALSO:Organic phosphorus compounds of the formula <FORM:0863380/VI/1> in which A1 and A2 are organic residues which are bound by a carbon atom to the phosphorus atom directly or through an oxygen, sulphur or nitrogen atom, R is a hydrogen atom or a C1-C4 alkyl group and Z is an oxygen or sulphur atom (see Group IV (b)) may be used as pesticides.

Filed: 1960-02-12
Abstract: 888,528. Stimulating urinary action. MC CRARY, L. I. Feb. 12, 1960, No. 5031/60. Class 81 (2). A device for stimulating normal urinary action comprises a closed liquid container 10 which has opposite transparent wall portions, an open-topped cup 14 in the upper part of the container and means for conducting liquid from the lower portion of the container to the cup which communicates with the lower portion through a restricted aperture 17.

Abstract: 1404405 Cinematography K VOCKENHUBER and R HAUSER 1 Feb 1973 [1 Feb 1972 2 June 1972] 5133/73 Heading G2E An intermittent film feed mechanism includes a film engaging claw 2 having a first component of motion along the length of the film generated by a follower 5 on cam 7 and a second component of motion causing film engagement and disengagement generated by a follower 14 on cam 18. In ONE revolution of the cam 7, the claw 2 will produce TWO complete reciprocations. One of these reciprocations in each cam revolution is selectively associated with the second component of motion. As shown the cam 18 has a single track 19 and the follower 14 may be moved by lever 21 between the position shown and position 14'. In one revolution of the track 19 a complete film engaging/ disengaging motion is performed. The positions 14, 14' associate this engaging/disengaging motion with a selected one of the reciprocations. The resulting two forms of film feed maybe used for feeding normal and super 8 film. In other embodiments the engagement cam may have two annular concentric tracks with the follower 14 switchable between them, Fig. 2 (not shown) or the lever moving the engagement cam follower may be of varied construction. In one embodiment Fig. 8 (not shown), the different forms of film feed correspond to forward and reverse film feeding.
Patent GB-867788-A (GB)
Title: Lysine derivatives
Filed: 1958-02-17
Abstract: The invention comprises the racemic and the D- and L-isomers of methyl-, ethyl-, propyl- and butyl- N,N1-ditrityl lysinate and their use in the production of a -peptides of lysine having the general formula:  <FORM:0867788/IV (b)/1> in which R is the radical of an amino acid or peptide containing the group -CH(NH2)-and R1 is OH, a lower alkoxy group or the radical of an amino acid containing the grouping -HN-CH(CO2H)- or a lower alkyl ester thereof.  The "lower" alkoxy and alkyl groups are those having less than 5 carbon atoms. The a -peptides having the general formula above are prepared by treating a lysine derivative of formula:  <FORM:0867788/IV (b)/2> in which X is a lower alkoxy group or the radical of a lower alkyl ester of an amino acid or peptide containing the group -NH-CH (CO2H)- with a trityl halide in an inert organic solvent and in the presence of an alkaline agent capable of taking up hydrogen halides, isolating the resulting N-N1-ditrityl lysine derivative, selectively detritylating it in the a -position by treating at elevated temperature in a mixture of an inert organic solvent and a mineral acid, isolating the resulting epsilon-N-trityl lysine derivative, condensing it with a trityl-substituted amino acid or peptide in the presence of dicyclohexylcarbodiimide and removing the protective trityl groupings from the resulting protected peptide of lysine so as to give a free a -peptide of lysine.  In order to produce the a -peptides in which R1 is OH it is necessary to saponify the ester group COX in which X is a lower alkoxy group.  Similarly the compounds in which X is the radical of a lower alkyl ester of an amino acid or peptide can be saponified to give the corresponding acids.  Preferably the selective detritylation is effected by a mixture of hydrochloric acid and acetone. Specifications 791,319 and 820,789 are referred to.

Filed: 1929-02-15
Abstract: 306,898. Vereinigte Aluminium- Werke Akt.-Ges. Feb. 27, 1928, [Convention date]. Wire of aluminium or aluminium alloy is made by first rolling and then drawing a bar of the metal, a fluid or gaseous agent such as cold air being applied to the work at its entrance into or during its passage through the rolling mill to prevent the temperature from rising to such an extent that recrystallization of the metal takes place. The maximum temperature attained by the bar during rolling is 300‹C. The wire may also be chilled before or after the winding operation. The rolling operation is continued till the work is about 6-6.5 mm. in diameter. The process is stated to produce a wire of uniform strength.
